OEM/ODM Custom Lost Foam Mold for Steel Casting Parts – ISO9001 Certified

This OEM/ODM lost foam mold is engineered to produce expendable foam patterns for custom steel casting parts. Manufactured in China under an ISO9001-certified quality system, the tool is machined from aluminum alloy and configured with steam and cooling circuits to support uniform bead fusion and clean pattern release. The mold can be built to customer drawings, with single or multi-cavity arrangements, and is intended for the lost foam casting route where the foam pattern is coated with refractory material, embedded in sand, and replaced by molten steel. The tooling is developed around the dimensional and surface requirements of the downstream steel casting process.

 Specifications

Mould Features

•  Custom Pattern Cavity – The cavity is machined to match the customer’s foam pattern drawing, including draft, parting, and core details suited to lost foam casting of steel parts.

• Aluminum Tool Body – The mold body is made from aluminum alloy, which provides rapid thermal response during steam heating and cooling, resists moisture in foam molding service, and keeps tool weight manageable.

• Steam and Cooling Circuits – Internal passages are arranged to deliver steam for bead expansion and water for cooling, helping maintain consistent foam pattern density and dimensions.

• Venting and Ejection Provisions – Vent paths and ejector locations are incorporated to promote complete cavity fill and allow clean removal of fragile foam patterns without damage.

• OEM/ODM Configuration – The tool can be supplied in single or multi-cavity layouts with replaceable inserts, adapting to different steel casting programs and production volumes.

Applications

• Automotive Steel Casting Patterns – Foam tooling for producing expendable patterns used in engine, transmission, and structural steel castings.

• Machine Tool Steel Casting Patterns – Molds for foam patterns applied to beds, columns, and housings in machine tool manufacturing.

• Industrial Pump and Valve Steel Casting Patterns – Tooling for foam patterns used in fluid handling and industrial machinery steel castings.

• Heavy Machinery Steel Casting Patterns – Molds for foam patterns applied to construction, mining, and agricultural equipment steel castings.

• Prototype and Trial Steel Casting Patterns – Tooling for development projects, process validation, and small-batch lost foam casting runs.

Our Advantages
1. We are the biggest lost foam mould manufacturer in China, we focus on high challenge lost foam mould and we have large gantry machining centers,30 sets imported high speed machining center,more than 40 sets general machine tool equipment;
2. We have 36 senior mould designers, to ensure reasonable / safety / high efficiency mould design and ensure the fast mould delivery and rational mould structure, make the process more safer and the production efficiency more higher;
3. We using numerical control machine tool to manufacture the mould cavities, to ensure a even thickness ;
4. We using ZL104 Aluminium to casting the mould, to manufacture a high strength mould;
5. For the big mould, we using Ø22*1 copper tube as cooling pipe, with water spray system, to get a nice cooling effect;
6. We Have (TEF10N) coating on the mould surface, it can reduce the friction, anti water/static electricity/acid-base/high-temperature, with this we can ensure the pattern has smooth surface without distrotion, and easy to demould;
7. All the screws we using stainless steel screw, easy to disassemble during maintenance;
8. For the big mould chest, we using 18-20mm thick wrought aluminium plate, to offer high strenght cavity ;
9. For the complex mould which is difficult to demould, we can manufacture the automaitc mould with take out device ;
10. We produce the pattern sample to customer after finish the mould, when the pattern was qualified, then we do exceptance job for the mould ;
11. We have the Hexagon coordinate measuring instrument imported from the Switzerland to have a test make sure our mould qualified.
